From the Call Of Duty Endowment Facebook page:
Tell us you "Like" the Call of Duty Endowment page over Memorial Day Weekend and we'll increase our grant funding to Hire Heroes USA by $1. The campaign will run until we reach $50,000 or the end of Memorial Day. (More details avail in our 'Notes)
So basically for every "Like" they get on face book, Activision will contribute $1 up to $50,000. As of this posting, there has been 15,723 people "liking" this.
